<p>I would greatly appreciate it if the Rust <a href="https://doc.rust-lang.org/nightly/rustc/platform-support.html">platform support page</a> was both 1) explicitly prescriptive and 2) explicitly descriptive and 3) clear about which is which. I just fixed up packed_simd's CI and there are some targets that functioned much more smoothly than others in the same tier, you know? And it's well-discussed that there's tier 2 and then there's "tier 2.5".</p>

<p><span class="user-mention" data-user-id="281757">@Jubilee</span> AFAIK there’s no 2.5 anymore, it was accidental in the first place. There’s the target tier policy RFC that is more prescriptive.</p>

<p>It still ~kind of~ exists (perhaps I should've said 2.25, or 1.75?) due to the hosts vs. targets gap, and testing is much more extensive for certain hosts or targets in practice. I will check out that RFC though, thank you!</p>
